Hi guys,
2.5.33 was fine, but from the boot messages (dual x86 box):
hda: IC35L020AVER07-0, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: host protected area => 1
hda: 39876480 sectors (20417 MB) w/1916KiB Cache, CHS=3323040/12/1
/dev/ide/host0/bus0/target0/lun0: p1 p2 p3
But it doesn't seem to have registered the third partition (/usr):
(none):~# cat /proc/partitions
major minor #blocks name
3 0 19938240 ide/host0/bus0/target0/lun0/disc
3 1 489951 ide/host0/bus0/target0/lun0/part1
3 2 128520 ide/host0/bus0/target0/lun0/part2
3 3 19318162 hda3
(none):~# ls -l /dev/ide/host0/bus0/target0/lun0/
disc part1 part2
Devfs issue? IDE screwage?
Rusty.

I see the same thing. Both of my IDE drives comes up without
the last partition. (Missing ide/host0/bus0/target0/lun0/part3
and ide/host0/bus1/target0/lun0/part7, loosing /usr and /usr/src
in my case.)
There's lots of updates in code that deals with partitions
and devfs, I couldn't find anything obvious wrong though.

devfs side. Fix:
